本文介绍了一种新型可溶性切削液，它不使用杀菌剂，但能抵抗微生物降解。生物抗性来自使用所有合成成分。在钻井寿命和车削（车床）试验中，新流体的性能与商业标准相似。在泡沫测试中，这种液体的性能也与其他商业可溶油一样，不会腐蚀铜或黄铜。它还能防止可锻铸铁生锈。乳状液可去除外源油（例如液压油或道路油）。当需要处理七氢硫酸或七氢硫酸镁时。水生试验表明，破乳后的水溶液对虹鳟鱼没有毒性。

THIS PAPER DESCRIBES A NEW SOLUBLE CUTTING FLUID THAT DOES NOT USE BIOCIDES YET RESISTS MICROBIAL DEGRADATION. BIORESISTANCE CAME FROM USING ALL SYNTHETIC COMPONENTS. IN DRILL-LIFE AND TURNING (LATHE) TESTS, THE NEW FLUID PERFORMED SIMILAR TO COMMERCIAL STANDARDS. IN A FOAM TEST, THIS FLUID ALSO BEHAVED LIKE OTHER COMMERCIAL SOLUBLE OILS AND IT DOES NOT CORRODE COPPER OR BRASS. IT ALSO PROTECTS MALLEABLE IRON FROM RUSTING. THE EMULSION REJECTS EXOGENOUS OILS (FOR EXAMPLE, HYDRAULIC OR WAY OILS). WHEN DESIRED FOR DISPOSAL, ACIDS OR MAGNESIUM SULFATE HEPTAHYDRATE (EPSOM SALT) WILL BREAK THE EMULSION. AQUATIC TESTS SHOW THAT THE AQUEOUS PORTION FROM A BROKEN EMULSION IS NOT TOXIC TO RAINBOW TROUT.
